Active vibration analysis of passenger biodynamics in quarter car model with summing ANFIS based PID super twisting control

Human health and safety issue is an interesting and challenging problem in travelling vehicles on road. Attenuation of whole body vibration (WBV) can be achieved by using various controllers in designed and developed vehicle systems. Hence, this research work is aimed at vibration analysis of passenger body under random road type developed using ISO 8608:2016 standard. Two controllers named as PID based super twisting control (PID-STC) and Summing ANFIS PID based Super Twisting control (SAPID-STC) are applied separately in suspension for vibration comparison of complete human body-quarter car system. The ride comfort analysis is performed using simulation results of human body response taking 2631-1:1997 standard. Numerical and graphical results clearly proved the superiority of SAPID-STC control in suppressing the undesired effects of vibrations on human body including discomfort, ride discomfort and motion sickness.
